Abstract

An epicyclical drive having a generally flat, disk shaped flywheel, a flywheel to pinion carrier in the form of an inner hub of the flywheel, and a flywheel support bearing and structure incorporated into the flywheel itself, all of which are concentric about a rotational axis of the flywheel so as to be axially compact, and so as to be particularly well adapted for being located beneath, or incorporated into, the floor of a grain header of an agricultural harvesting machine, for reciprocatingly driving knife knives of a sickle thereof. In particular, the flywheel support bearing is located in an annular space between the inner hub and an outer flange which is rotated by a belt or other drive for rotating the flywheel.

Description

TECHNICAL FIELD

[0001] This invention relates generally to an epicyclical drive, and more particularly, to an epicyclical drive having a flywheel, flywheel to pinion carrier, and flywheel support bearing and structure, which are concentric about a rotational axis of the flywheel and which are axially compact, so as to be particularly well adapted for being located beneath, or incorporated into, the floor of a grain header of an agricultural harvesting machine, for reciprocatingly driving a sickle thereof.BACKGROUND ART

[0002] Epicyclic drives are noted for their utility for converting rotary motion to reciprocating linear motion, in a variety of applications. For example, epicyclical drives are used for driving reciprocating sickles. Sickles are commonly used on agricultural harvesting machines, including on the headers of combines and windrowers. Such sickles typically include cutter bars supporting a row of knives, have been used to cut plants, including, but not limited to, hay, gras...
